American painter, b. Russia. At 10 he accompanied his family to Brooklyn, N.Y. He studied art at Pratt Institute and in 1905 went abroad. In Paris he studied under J. P. Laurens, later visiting Spain and Italy and returning to New York in 1909. Weber's work in the following decade was fauvist and then cubist inspired. Characteristic of the latter trend is his well-known Chinese Restaurant (Whitney Mus., New York City). He began to introduce Jewish subjects into his work c.1917. During the 1920s, Weber alternated painting with teaching. Contemporary and social themes were his subjects in the 1930s, when his work became increasingly abstract and revealed a new energetic use of line. Weber is represented in leading galleries throughout the United States. He wrote several essays on art theory.
